Shares of interest rate-sensitive companies rallied on Wednesday amid optimism of a more dovish monetary policy following the appointment of Shaktikanta Das as the new governor of the RBI.

Analysts at Kotak Institutional Equities observe the sudden resignation of Urjit Patel as RBI governor seems to have perceived casually by the market. Patel had resigned on Monday, citing personal reasons for his sudden exit. Reacting to the appointment of new governor, the bonds too surged. Marking its second day of gains, the yield on 10-year bonds dropped 12 basis points to 7.41%. \u201cThe market perhaps believes that the departure of the RBI governor could lead to a relaxation in certain regulations for the banking sector and a more liberal monetary policy,\u201d Kotak Institutional Equities wrote in a note. Liberal monetary policy is perceived to be a relief for automakers and real estate firms which have been battling a fall in sales due to sluggish economic growth, high interest rates, and an increase in raw material and fuel prices. Despite November being a festive month, Hero MotoCorp had posted less than 1% increase in its sales. \u201cThe industry witnessed conservative sales off-take during the previous couple of months owing to issues like increase in insurance costs before the festive season and overall low key market sentiment. However, sales picked up in the last few days of the festive season,\u201d the company said during the announcement of November sales numbers.
